GSO ISO/ASTM 51940:2017 Scope
1.1 This guide outlines dosimetric procedures to be followed
for the radiation-induced reproductive sterilization of
live insects for use in pest management programs. The primary
use of such insects is in the Sterile Insect Technique, where
large numbers of reproductively sterile insects are released into
the field to mate with and thus control pest populations of the
same species. A secondary use of sterile insects is as benign
hosts for rearing insect parasitoids. The procedures outlined in
this guide will help ensure that insects processed with ionizing
radiation from gamma, electron, or X-ray sources receive
absorbed doses within a predetermined range. Information on
effective dose ranges for specific applications of insect sterilization,
or on methodology for determining effective dose
ranges, is not within the scope of this guide.
NOTE 1—Dosimetry is only one component of a total quality assurance
program to ensure that irradiated insects are adequately sterilized and fully
competitive or otherwise suitable for their intended purpose.
1.2 This guide provides information on dosimetry for the
irradiation of insects for these types of irradiators: selfcontained
dry-storage 137Cs or 60Co irradiators, self-contained
low-energy X-ray irradiators (maximum processing energies
from 150 to 300 keV), large-scale gamma irradiators, and
electron accelerators (electron and X-ray modes).
NOTE 2—Additional, detailed information on dosimetric procedures to
be followed in installation qualification, operational qualification, performance
qualification, and routine product processing can be found in
ISO/ASTM Practices 51608 (X-ray [bremsstrahlung] facilities processing
at energies over 300 keV), 51649 (electron beam facilities), 51702
(large-scale gamma facilities), and 52116 (self-contained dry-storage
gamma facilities), and in Ref (1) (self-contained X-ray facilities).
1.3 The absorbed dose for insect sterilization is typically
within the range of 20 to 600 Gy.
1.4 This guide refers, throughout the text, specifically to
reproductive sterilization of insects. It is equally applicable to
radiation sterilization of invertebrates from other taxa (for
example, Acarina, Gastropoda) and to irradiation of live insects
or other invertebrates for other purposes (for example, inducing
mutations), provided the absorbed dose is within the range
specified in 1.3.
1.5 This guide also covers the use of radiation-sensitive
indicators for the visual and qualitative indication that the
insects have been irradiated.
1.6 This document is one of a set of standards that provides
recommendations for properly implementing and utilizing
dosimetry in radiation processing and describes a means of
achieving compliance with the requirements of ASTM Practice
E2628. It is intended to be read in conjunction with ASTM
E2628.
1.7 This standard does not purport to address all of the
safety concerns, if any, associated with its use. It is the
responsibility of the user of this standard to establish appropriate
safety and health practices and determine the applicability
of regulatory limitations prior to use
